Variable Refrigerant Flow (VRF) heat pumps are gaining more recognition as a highly efficient system for heating and cooling applications. These are advanced heat pump systems with the option of heating and cooling/dehumidification simultaneously as well as recovering heat, called VRF 3-pipe systems. Zoning with individual control and minimal or no ductwork are the main advantages of these systems which could be an ideal choice for multi-zone commercial buildings. The system consists of a single outdoor unit and multiple indoor units for each zone plus refrigerant piping and branch selector boxes. The all-electric systems have been around for more than two decades in North America and are being offered by some manufacturers.
Natural-gas engine-driven VRF heat pumps (GEHP) as compare to all-electric systems are energized by an internal-combustion engine in place of an electric motor. They provide the advantages of VRF heat pump systems by using a low-cost natural gas energy source.
